Preimplantation Diagnosis (PGD) is the only clinically valid genetic screening test based on massive next generation sequencing. It is the most comprehensive and accurate test available.
PGD is an option for couples whose offspring are at high risk of developing a serious hereditary disease.
Preimplantation genetic diagnosis (PGD) is a genetic examination of the embryo before (pre-) implantation in the uterus. For this purpose, certain cells are removed from the embryo approximately five days after fertilization and genetically examined. The removal of these cells does not usually harm the embryo. Embryos that are unaffected by the genetic change being studied are then selected for transfer to the woman’s uterus.
Even if there is no fertility problem, artificial insemination (IVF/ICSI) is still required for PGD in order to examine the embryos in the laboratory.
